DECOR: DECORATING WITH TABLE LAMPS

Lamps not only serve as a source of light, they also can be decorative elements in a room. A lamp can add ambience and finish off a room, but should be the proper size. The correct height of a lamp depends on the room, the size of the table and the use of the light. A balance in the size of a lamp and the furnishings around it is key.

A smaller lamp looks best when placed on a small accent or side table. A slender candlestick lamp is appropriate for a side table that is slim and delicate in style. The lamp's base also should be sized for smaller side tables; if the base is too wide, it could be knocked off of the table easily. If a side table is placed next to a chair, the height if the lamp should be considered.
